10.9.4 - Thunderbolt display for 6630M (Mini mid-2011) still broken

10.9.4 has failed to fix what was fine in 10.9.2 and broken starting with 10.9.3 -- a display (Dell U3011) connected to a Mac Mini mid-2011 via either a DisplayPort cable or dual-DVI adapter suffers from frequent loss of signal. The elsewhere-prescribed-juju of changing spaces, unplugging and replugging cables, ... works randomly and for short duration.

HDMI connection works (producing non-native resolution on the U3011).

This was filed as bug 17083693 and closed as a duplicate of 16197028.

Same problem here. This has been a huge disappointment. We use our iMac (newest gen) to run the media system for our church. Since 10.9.3 it's been a nightmare. We have 1 TB display, and 2 external outputs that are 70' tvs (2 in the front that are ran off of a splitter and 1 in the back). the FOH tv's stopped working. I've had to stop using the stage display and buy another splitter to split the only working external output to now show the same content to all tv's.. Come on Apple, Please give use what we had in 10.9.2 back.

This thunderbolt external display problem is a nightmare, we should combine all threats related to it shouldn't we?

It seems like these threads, at least, also complain about this issue potentially:

https://discussions.apple.com/thread/6048015

https://discussions.apple.com/thread/5971536

https://discussions.apple.com/thread/6397766

https://discussions.apple.com/thread/6280850

https://discussions.apple.com/thread/6224423

and in later posts here:

https://discussions.apple.com/thread/5469819

I have no idea how to inter-relate them (or if it's possible in this forum software) so that someone reading one of these (or this) threads would be redirected to a master thread...

(I'd be happy to combine all threats into one massive, albeit sadly still impotent, threat.)

Please, add my complain too, I'm very frustrating and angry in how Apple handle with us costumers, we paid for quality products And nothing seems right anymore, I'm afraid Apple it's not the same...

Second display problem with 10.9.4

Just got off the phone with support, then senior support. Tried all the usual's, SMC reset, PRAM reset, port tests....

Used a program sent to me to capture my system settings. Uploaded it to engineering.. More to come........
